Abstract

Blade serving, in general, for wiping any surface, in particular for windscreen wiper use. The shape of the blade in the free state is such that once it is installed, the portion which is reserved for wiping exerts a pressure at all points on the surface to be wiped, following its own elastic deformation. Main applications: motor vehicle, aeroplane and boat windscreen wipers.

Description

Titre :LAME D'ESSUYAGE SOUPLE
SECTEUR DE LA TECHNIQUE.Title: FLEXIBLE WIPING BLADE
TECHNICAL SECTOR.

La lame d'essuyage souple est un organe destiné à assurer la fonction d'essuyage de toute surface devant être débarassée des poussières, impuretés ou liquides qui la couvrent. The flexible wiping blade is a member intended to ensure the wiping function of any surface which must be rid of dust, impurities or liquids which cover it.

ETAT DE LA TECHNIQUE.STATE OF THE ART.

Dans la plupart des cas la fonction essuyage est assurée par un essuieglaces,constitué d'un bras rigide ou de plusieurs bras articulés entre eux et portant un profilé en élastomère en contact avec la surface à essuyer. In most cases, the wiping function is ensured by a wiper, consisting of a rigid arm or of several arms hinged together and carrying an elastomer profile in contact with the surface to be wiped.

La qualité du contact surfaoe-profilé est plus ou moins bien assurée,en fonction de la forme de la surface à essuyer et de la vitesse d'essuyage. The quality of the surface-profile contact is more or less well assured, depending on the shape of the surface to be wiped and the wiping speed.

BUT DE L'INVENTION. PURPOSE OF THE INVENTION.

La lame d'essuyage souple remédie aux défauts des essuieglaces actuels:Mauvaise répartition de la pression d'essuyage,variation de la pression au cours du cycle d'essuyage;tout en apportant d'autres avantages. The flexible wiping blade remedies the faults of current wipers: Poor distribution of the wiping pressure, variation of the pressure during the wiping cycle; while bringing other advantages.

Les articulations et ressorts divers de l'essuie glaces traditionnel sont remplacés par une lame déformable en tout ses point afin d'assurer une pression de contact dont la valeur et la loi de répartition est déterminée de construction. The various articulations and springs of the traditional windscreen wipers are replaced by a deformable blade at all its points in order to ensure a contact pressure whose value and the distribution law is determined by construction.

De plus,la lame d'essuyage souple permettra d'obtenir:
-Une réduction des coûts de fabrication par suite de la simplification et de la réduction du nombre de pièces à fabriquer.In addition, the flexible wiping blade will provide:
-A reduction in manufacturing costs as a result of the simplification and reduction of the number of parts to be manufactured.

-Une masse réduite de l'ensemble mobile,permettant une diminution de puissance de la motorisation ou une augmentation de la vitesse d'essuyage,à puissance égale. -A reduced mass of the mobile assembly, allowing a reduction in power of the motorization or an increase in the wiping speed, at equal power.

-Une emprise aérodynamique réduite, apportant une amélioration de l'essuyage à haute vitesse et un coefficient de forme globalement réduit pour un véhicule équipé de telles lames.  -A reduced aerodynamic grip, providing an improvement in wiping at high speed and a generally reduced form coefficient for a vehicle equipped with such blades.

MOYENS MIS EN OEUVRE.MEANS USED.

La lame d'essuyage souple est une pièce flexible portant à son extrémité (ou en plusieurs endroits) une pièce de fixation ou d'articulation. The flexible wiping blade is a flexible piece carrying at its end (or in several places) a fixing or articulation piece.

Une partie de la longueur est destinée à porter un balai d'essuy age,généralement en élastomère,ou à assurer directement l'essuyage. A part of the length is intended to carry a wiper blade, generally made of elastomer, or to directly ensure wiping.

L'ensemble de la lame pivote autour de l'articulation précitée ou décrit un mouvement quelconque communiqué par ses fixations. The entire blade pivots around the aforementioned articulation or describes any movement communicated by its fixings.

A l'état libre (non installée en position de travail),la forme de la fibre neutre de la lame est prévue de telle façon,qu'une fois installée sur ses fixations ou articulations la partie réservée à l'essuyage de la lame exerce une pression déterminée en tout ses points sur la surface à essuyer,par suite de la propre déformation élastique de la lame. In the free state (not installed in the working position), the shape of the neutral fiber of the blade is provided in such a way that, once installed on its fixings or joints, the part reserved for wiping the blade exerts a pressure determined at all its points on the surface to be wiped, due to the own elastic deformation of the blade.

La forme de la lame à l'état libre est toujours différente de la forme de la surface à essuyer,la force d'appui en tout point étant potentiellement contenue en tout point correspondant de la lame,du fait de sa courbure différente de celle de la surface à essuyer. The shape of the blade in the free state is always different from the shape of the surface to be wiped, the bearing force at any point being potentially contained at any corresponding point of the blade, due to its curvature different from that of the surface to be wiped.

Ce système s'oppose à tout système comprenant une lame courbe maintenue par des biellettes,l'utilite' de ces biellettes étant,en fait de communiquer une partie de la force exercée extèrieurement à la lame à divers endroits de celle.  This system is opposed to any system comprising a curved blade held by rods, the utility of these rods being, in fact to communicate a part of the force exerted externally to the blade in various places of that.

La figure -1- illustre le cas d'un essuieglaces de véhicule réalisé suivant ce principe:
-En -la- est figurée la forme de 1 'essuieglaces à l'état libre.Figure -1- illustrates the case of a vehicle wiper produced according to this principle:
-In -la- is shown the shape of one wiper in the free state.

-En -Ib- est figuré l'essuie-glaces en position de fonctionnement. -In -Ib- is shown the wiper in operating position.

La pression entre la lame et la surface à essuyer peut etre constante sur toute la longueur ou être évolutive,par exemple:
-Pression faible près de 1 'articulation,là où la vitesse est faible.The pressure between the blade and the surface to be wiped can be constant over the entire length or be scalable, for example:
-Low pressure near the joint, where the speed is low.

-Pression élevée à l'extrémité de la lame,là où la vitesse est élevée. -High pressure at the end of the blade, where the speed is high.

Les matèriaux utilisés pour la fabrication de telles lames sont divers,l'utilisation de matèriaux fibreux à matrice polymère ou autre matrice permet d'absorber les grandes déformations mécaniques exigées pour la qualité du système,tout en acceptant des taux de contrainte élevés.  The materials used for the manufacture of such blades are diverse, the use of fibrous materials with polymer matrix or other matrix makes it possible to absorb the large mechanical deformations required for the quality of the system, while accepting high stress rates.
